BUTTON-SETTING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 294,744, dated March 4,1884.

Application filed January 4, 1884. (No model.)

T0 aZZ whom it may 6071108772,."

Be it known that I, GEO. W. 'PRENTIcE, a citizen of the United States,residing at Provideuce, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Dies forSetting- Instruments; and I do hereby declare the folof the invention,such as will enable others skilled in the art to which it appertains tomake and use the same,,reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

My invention relates to button-setting instruments; and it consists of adie having a peculiar form adapted to be wrought or formed in one of thejaws or members of the instrument, whereby one of the prongs of atwopronged button-fastener is first deflected and bent parallel with andunder the table or body of the fastener, after which the other prongthereof is adapted, by means of the concave portion of said die, to bedeflected beneath the former prong and at right angles therewith, andalso clinched thereto, the fastener then approximating an :fi-shapedform.

My invention further consists in means for retaining the button, &c., inthe instrument during the operation of attachment, all as will be morefully hereinafter set forth.

In the accompanying sheet of drawings, Figure 1 represents a front viewof a buttonsetting instrument provided with myimprovement, showing abutton and fastener in position for attachment to the fabric, a portionof each jaw being in section. 7 Fig.2 represents a top view of the same,with button and fastener removed. Fig. 3 represents a front View of theinstrument, showing the fastener clinched beneath the fabric, a portionof the upper jaw being removed. Fig. 4 represents a top view of thelower jaw, showing my improved clinching-dies formed therein. Fig. 5represents, enlarged, a cross-section through 0 o of Fig. 4, showing theconcave portion of my improved die. Fig. 6 represents a cross-sectionthrough- :0 w of Fig. 3. Fig. 7 represents a button-fastener after beingbent and clinched with my improved die. Fig. 8 represents a plan view ofthe end of the lower jaw, showing the con cave portion of theclinching-die parallel wit-h the jaw.

The object of my invention is to furnish means, consisting of dies ofpeculiar shape in the jaw of a setting machine or instrument, wherebyfasteners having two prongs may be. inserted through the fabric andclinched thereunder, my invention being more particularly adapted to beused with that class of fasteners represented in V. II. Hazels patent,No. 259,656, of June 13, 1882.

The following is a description of my invention and its operation: I.

A in the drawings represents a button-setting instrument, consisting ofthe j aws or members a b, terminating, respectively, in handles a b. Theupper surface of the lower jaw, b, has formed or secured therein at itsend I) the longitudinal diegroove z, the outer end of said die beingslightly concave, the die also being of uniform depth throughout, andadapted to deflect and receive the long prong a of the fastener n.

2 represents a concave and nearly semicircular-shaped die formed in saidjaw 12 at right angles to and bisecting the said die 2, the die 5 beingadapted to deflect and receive the short prong a of said fastener.

That portion of the upper jaw, a, which retains the button and fasteneris divided longitudinally into two parts, the front portion, a thereofbeing pivoted at g.

d d represent recesses formed at the outer end of the jaw a, adapted toretain the button B and its fastener a during the operation ofattaching. To the inner arm, c of said lever a is formed a wedge or camshaped projection, 6, adapted to engage with a similar and correspondinglug, e, of the lower jaw, as fully shown.

The following is the operation of my invention: The end (def the lever ais depressed, thereby opening the jaw for the purpose of placing thebutton with its fastener a therein, the spring 8 serving to assist inretaining them in position; The fabric or leather to which the button isto be attached is now placed in position beneath the depending fastener,when, by compressing the jaws of the instrument, the end a of the longprong of said fastener is first inserted through the fabric, and, comingin con- IOC 2 QWLVdd tact with the curved end of the die a, is deflectedalong said die and beyond the concave portion thereof. At or about thisstage of the operation the end of the short prong n" of the fastener isforced through the fabric and engages with the outer edge of the concavedie z, when, finally, by now fully closing or contracting thejaws, thelatter prong is forced beneath and partially around the long prong, asfully represented in Fig. 3, thus approximating an (:11 form. During thelatter part of the clinching operation the wedges e c of the jaws engagewith each other, thereby rigidly holding the button and fastener inposition within the upper jaw. By depressing the lever the fabric,withits attached button, is released from the instrument.

The fastener shown in Fig. 7 is adapted to he clinched by means of myimproved dies, or, in fact, any fastener of that class having twounequal prongs which are offset or not in line with each other.

I do not claim, broadly, a button-fastener clinched as represented, butask protection for the setting-instrument provided with the dies adaptedto clinch the prongs in the form and manner shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In abutton-setting machine or instrument provided with means forretaining a button and fastener in position, the prong-deflecting deviceherein described, consisting of the dies .3 c the latter having aconcave form, and arranged at right angles with and crossing the diesaid dies being formed in ajaw or member of said instrument,substantial] y as shown, and for the purpose set forth.

2. The button-setting instrument A, herein described, consisting ofthejaws a I), the former being provided with the pivoted supplementallever or jaw a and the jaw Z) being provided with the clinching-dies zand cam projcction 0, the whole combined and arranged substantially asshown, and for the purposes set forth.

3. In a two-jaw button-setting instrument provided with clinching-diesand wedge e, and further provided with means for retaining a button andpronged fastener in posit-ion, the combination therewith of asupplemental lever adapted to be pivoted to the button-holding jaw, andhaving a wedge or cam, (1, adapted to engage with the wedge e of itsfellow jaw, substantially as shown, and for the purpose described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
